This book was released on 1982 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Satellite infrared imagery off the California coast, near Pt. Sur, show thermal patterns associated with an upwelling center; the patterns frequently curl cyclonically when interacting with the warmer California Current. This pattern shows sharp thermal fronts, easily identified in satellite IR images, that are strongly correlated with nutrient fronts during the early stages of upwelling. With sea truth data available, it was feasible to calibrate satellite derived sea surface temperature, by applying radiative transfer theory, and to infer nutrient concentrations from their linear inverse correlations with temperature. Thus, it was possible to calibrate satellite thermal fields to produce maps of nutrient distributions. When the inferred relationships were applied over representative regions of the upwelling center, standard deviations of 0.5C, 1.7 microns and 0.1 microns were computed for temperature, nitrate and phosphate, respectively.

This book was released on 1979 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the study of ocean fronts and eddies has become increasingly important to the U.S. Navy for they are of vital importance in understanding underwater sound transmission. From the history of satellite pictures for the area of the ocean off the central California coast, it appears that cold water which has come to the surface as a result of upwelling has become intertwined within the California Current. The persistent thermal features in the sea surface which are formed were the subject area of this study. Direct telephone contact was established with the satellite receiving station which afforded real time satellite information as to the thermal structure of the sea surface on a mesoscale. This satellite sensed thermal structure was then compared with in situ nutrient and temperature data collected on three cruises on board the research vessel ACANIA. The agreement between the in situ data and the satellite imagery was very strong and the utilization of satellite imagery was shown to be a very effective method to localize an ocean front.

This book was released on 1979 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of this research was to perform an analysis of the constancy of the sea-surface temperature in candidate locations for OTEC siting. Most in situ data available to determine the constancy of the sea surface temperature were obtained using point sensors that recorded surface temperature at specific points and at specific times or for some specific period. These data, while establishing certain gross or average patterns, are inadequate for describing short-term temperature variations for large areas and are insufficient for assessing the constancy of the temperature patterns relative to selecting potential sites for OTEC. The only data available for analysis of the synoptic ocean surface temperature pattern are those obtained in the last five years by infrared scanning radiometer systems on earth observational satellites. For this study, the satellite infrared (ir) data for the period 1973-1977 were used to identify and locate major thermal fronts at the sea surface. These data were then used to glean certain statistics on these fronts. In situ data were used, when available, to determine temperature difference across specified thermal fronts. This study was performed in three regional locations of interest to OTEC. The specific regions are: Region I, Eastern Gulf of Mexico (bounded by 22 N to 30 N and 91 W to the west coast of Florida including the Straits of Florida); Region II, the east coast of Florida (bounded by 23 N to 32 N and the east coast of Florida to 79 W); and Region III, Puerto Rico and vicinity, (bounded by 17 to 19 N, 64 to 68 W). Results are presented and discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The sea surface temperature field of a 10 x 20 degree area of the North Atlantic is constructed from synoptic temperatures of the ocean surface obtained from High Resolution Infrared Radiometer (HRIR) data from NIMBUS II meteorological satellite. The computer analysis of these satellite data is compared with the computer analysis of three and one half days of conventional ship data produced for the same time period by the Fleet Numerical Weather Central (FNWC), Monterey, California, with a manual analysis of the same ship data prepared by the Fleet Weather Central, Norfolk, Virginia, and with an experimental numerical analysis done by NAVOCEANO.

Available in PDF, EPUB and Kindle. Book excerpt: Satellite technology represents the only technique for measuring sea surface temperatures (SSTs) on a global scale. SSTs are important as boundary conditions for climate and atmospheric boundary layer models which attempt to describe phenomena of all scales, ranging from local forecasts to predictions of global warming. Historical use of infrared satellite measurements for SST determination has been based on a theory which assumes that the atmosphere is 'thin', i.e., that atmospheric absorption of infrared radiation emitted from the sea surface has very little effect on the radiant intensity that is measured by satellites. However, a variety of independent radiative transfer models point to the possibility that the so-called 'thin approximation' is violated for humid atmospheres such as those found in the tropics, leading to errors in the retrieved SST that would be unacceptable to those who make use of such products. Furthermore, such tropical regions represent a significant portion of the globe, where coupled ocean-atmosphere disturbances can have global effects (e.g., the tropical Pacific El Nino-Southern Oscillation events). This study evaluates the thin approximation empirically, by combining radiative transfer theory and satellite data from the Eastern Atlantic ocean region studied during the Atlantic Statocumulus Transition Experiment (ASTEX). Six months of satellite data from May, June, and July of 1983 and 1984 are analyzed. To the degree that the data may be considered representative of globally valid relationships between measured variables, it is shown that the thin approximation is not appropriate for the tropics. This suggests that new methods are necessary for retrieving SSTs from the more humid regions of the globe.

May and published by . This book was released on 1988 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 1987, two Expanded Ocean Thermal Structure (EOTS) analysis runs were made daily at 12Z for 5 consecutive days. These runs were made offline at the FNOC for the ENOTS Gulf Stream region. All available satellite multichannel sea surface temperature (MCSST) retrievals, ship reports, and expendable bathythermograph observations were assimilated into the first analysis, with MCSSTs withheld from the second to determine satellite data impact on the analysis. Aircraft-launched expendable bathythermograph (AXBT) data from coincident Regional Energetics Experiment flights were used as independent ground truth. The analysis results and input data sets were compared to the AXBT data. This study shows that MCSST data significantly add to the accuracy of front and eddy mapping by tightening up strong frontal gradients and reducing the impact of relatively noisy ship data. The reliability, the accuracy, and the quantity of MCSSTs far exceed that of ship reports. This difference is evident in the better identification of significant oceanographic features by the satellite-aided analysis. Accuracy of regional EOTS analysis was found to be severely degraded when the only available MCSST data are over 48 hours old. Keywords: Infrared radiation remote sensing, Thermal analysis. (edc).
